New York City, 1924: the height of Prohibition and the whole city swims in bathtub gin.
Rose Baker is an orphaned young woman working for her bread as a typist in a police precinct on the lower East Side. Every day Rose transcribes the confessions of the gangsters and murderers that pass through the precinct. While she may disapprove of the details, she prides herself on typing up the goriest of crimes without batting an eyelid.
But when the captivating Odalie begins work at the precinct Rose finds herself falling under the new typist's spell. As do her bosses, the buttoned up Lieutenant Detective and the fatherly Sergeant. As the two girls' friendship blossoms and they flit between the sparkling underworld of speakeasies by night, and their work at the precinct by day, it is not long before Rose's fascination for her new colleague turns to obsession.
But just who is the real Odalie, and how far will Rose go to find out?
